2 Application filed May 31,

To all whom it may concern: 7

Be it known that I, HARRY L. BRADLEY a citizen of theUnited States, residing at Milwaukee, county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Lavatories, of which the following is a specification.

My invention relates toimprovements in lavatories. The general object of this .de- 7 vice is to provide an improved lavatory. for use primarily in factories, schools and pub-v lic or other buildings bya number of persons at the same time, which shall beclean,

7 provide a fresh, vclean supply'of runnin vidual wash bowls. All of these devices are open to serious objectionswhich my invention is designed to overcome. bowls are of necesslty used by several men in succession without adequateropportunityi or PIOVlSlOIlf for sterllizatlon or cleaning,

andif there 13 any lnfection in the first user it is apt tospread to thesubsequen't users. The different forms of" troughs are even more open to. the same objection in that the contamination from one user spreads throughout the common water supply and contaminatesthe others. 7

My device is designed to give a lavatory; that is sanitary, is easily cleaned, in which there is a'constantly replenishingsupply of pure water, and so arranged that each user gets fresh water directi-from the supply without contamination from the V otherv users or from thesides or bottom of the receptacle. In designing lavatoriesof this kind it is important that the fresh watersupply be so arranged that noneof the water falls back upon itself. If the supplyof water in its downward path Imingles with the fresh water in its upward path the soap, dirt, and any contamination there may be mingles with and contaminates the pure water sup-v ply and also tends to form pockets or eddies pension and prevent jthe complete and immediate runoff. Furthermore, the water, mustbe so supplied as to be freely and uninterruptedly flowing at, an even anddewheel which operates the shut-off valve 6, '7

terminable height, .whereasif it falls back upon itself or thestreams cross the flow is made irregular, at times theflow: is detained and there is but little water available, and again the pocket seems to: breakandsthe water' sho'otsup to great heights, splashingm either outside of the receptacle or: into-the5= faces of the users thereof Referring specifically to the drawings which form a part of this-specification, Figure 1 is a verticalsection on-v the line 1-1,-

Fig. 2, of a lavatory embodying the invention; Fig. 2 is a plan view of the lavatory;

Figs. and 4 show modified forms of fountain withmeans'for adjusting or. determin:

,ing the height and the relative rate "of flow Fig. 6 is a planview of the same..-

In Fig. 1, 1 is the basin orreceptacle of r the lavatory,-2 is the; fountaintherein, 3 is Buckets and wash the intake piping, 4 is the strainersand drain,'waste or outlet piping, 5 is the hand is the mixer which is connected-with the valve 6 and whichroperates toregulatethe temperature of the water or relative pro-- portions ofhot and cold water admitted to the lavatory. The intake piping--3 passes upwardly through-an enlarged fitting or sec-:-

tionof the outlet pipei l, sothata single opening in the bottom of the receptacle 1 suffices for theconnection therewith of: the

-water supply'and waste. In operation the valve. 6 is firstyopened so. as: to admit the amount .of water rdesired, the; rate of flow: being controlled thereby, and the mixer 7 is then operated to produce the required degree of warmth; The water issues from :the ori-' fices in the fountain 2, which isadapted to throw upwardly and outwardly orobliquely therefromsmall, thin or finejets or streams of water in the form of an inverted frustum of a cone, so that when the streams; reachthe point of-their-maximum elevation and begin to fall downward they do so outside or clear of the periphery of the fountain 2,

ber of persons may use the. lavatory at the sametime and each obtain a sanitary flow of running water without contamination from the othersand without contamination from the deposit on the sides and bottom of the lavatory such as forms in lavatories in which'water stands when being used for washing. The strainer and waste pipe 4; are of ample size to carry off the water as fast as it falls upon the bottom of the receptacle 1, thus preventing the backing up of' any used water therein. The fountain 2 is preferably made in annular form wlth the center open, as shown in Fig. 2, so as to afford no dead space or surface 1n or on which dirty water and germs can accumu It is often convenient to have the sldes This may be done either by varying the size,

shape, or angle of the respective series of orifices as shown in Fig. 1; by providing separate water supplies to each of the an: nular spaces 9 with a separate cook or adjusting means 10 for regulating the relative rate of flow thereto as shown in'Fig. 3; or the inside set of orifices may be elevated sufliciently above the outside set of orifices to produce this result as shown in Fig. a. In the drawing two sets of orifices only are shown, but the device. can operate with either one set or with three or more. not limit myself to the use of two.

In designing the receptacle 1, it may, if desired, be made as shown in Figs. 5 and 6 by using a pan or basin 1' or similar device at the bottom for catching the water and surrounding it with a curtain or splash shield 11 supported on a circular rod 12. In any event the portion of the device that rests upon the floor should be made as shown, to afford a recess into which the users feet can extend. It is also important that the edge of the lavatory or the rod 12 supporting the shield, if that form is used, be of suflicient height and strength to afford a support or rest for users; so that in leaning over the lavatory the knees or other parts of the bodies of users may rest thereon and prevent them from accidentally being precipitated into the lavatory. If desired soap dishes may be hung on the edge of the lavatory on the inside thereof so that the water therefrom will drain into the lavatory and out through the drain pipe 4.

Having fully described my invention, I claim:

1. In a lavatorythe combination of a re- Ido ceptacle provided with a waste outlet leading from the lower part thereof, and a fountain located within said receptacle and provided with a water supply connection and adapted to project upwardly and obliquely a plurality of closely associated non-interfering fine streams of water and to cause them to fall inertly, clear of the fountain, into the receptacle, without the falling streams mixing withthe upwardly projected streams.

2. In a lavatory the combination of a receptacle provided with a waste outlet leading from the lower part thereof, and a fountain located centrally within said receptacle and provided with a water supply connection and with jet orifices adapted to project upwardly and outwardly parallel series of closely associated non-interfering fine streams of water and to cause them to fall inertly clear'of the fountain into the receptacle between the fountain and the margin of the receptacle without the falling streams mixing with the upwardly projected streams.

3. In a lavatory the combination of a receptacle provided with a waste outlet, a fountain located within the receptacle and provided with a water supply connection andwith jet orifices adapted to project upwardly and obliquely parallel series of closely associatedfine streams'of water and to cause them to fall inertly into the receptacle clear of the fountain, and means for determining the relative altitude to which the streams of difierent series are projected from the fountain.

4. In a lavatory the combination of a receptacle provided with a waste outlet and formed to receive beneath it the feet of users,

and a fountain located within the receptacle and adapted'to project upwardly and outwardly from the fountain a plurality of non-interfering fine streams of water and to cause them to fall inertly clear of the fountain into the receptacle between the fountain and the margin of the receptacle without the falling streams mixing with the upwardly projected streams. I

5. In a lavatory the combination of a receptacle provided with a waste outlet and above the base with a rest for users, and a fountain provided with a water supply conadjacent said centrally located in said receptacle and provided with a water supply connection and with jet orifices adapted to project upwardly and outwardly therefrom a series of fine streams of water and to cause them to fall inertly into the receptacle between and clear of the fountain and the margin of the receptacle adjacent said rest.

7. In a lavatory the combination of a re ceptacle provided with a waste outlet leading therefrom and a fountain provided with a water supply connection and adapted to project upwardly a plurality of non-interfering fine streams of water and cause them to fall in close association with one another inertly into the receptacle clear of the fountain and of the ascending streams without the falling streams mixing with the upwardly projected streams.
